Serial No. 624,316.

To all whom it may concern:

Be it known that I, ANDREW \JOHNSON, 9. subject of the King of Sweden, residing in Jamestown, Chautauqua county, State of New York, have invented certain new and useful Improvements in Sheet-Metal Doors and the Like, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had'to the accompanying drawings, forming part of this specification.

.My invention relates to doors, and the like, that are made from sheet metal which is formed into shape rolled and Welded so as to make a substantial Structure.

The particular objects of the invention are to construct a door of this class, of comparatively light weight and at the same time with high power of resistance to'strains and warping and to make the same of great durability.

With these and other objects in view my invention consists of the various novel and peculiar arrangements and combinations in the difi'orcnt parts of the structure, all as hereinafter fully set forth and then pointed out in the claims.

I have illustrated types of my invention view of the top rail, the plane of the section being indicated by line 33, Fig. 2. Fig. 4, is a horizontal sectional View, the lane of the section being through the centra rail, as indicated by line 4-4, Fig. 1. Fig. 5, is a vertical sectional view on a plane through the hinge-stile, and at right angles to the section of Fig. 4.

Referring to the drawings, in which like numbers of reference designate like arts throughout, 1 is the hinge-stile, 2 the 00kstile, and 3, 4 ,and 5, are the top, central and bottom rails, respectively, with the panels disposed between such parts and ornamental molding formed along the inner edges of the stile and rails and around such panels. The stiles, rails, moldings and usually the panels are made of sheet metal, such for example as steel, formed into hollow bodies as Wlll now be described.

The hinge-stile is a hollow member having the three sides 6, 7 and 8, and the lockstilc is substantially similar to this and has the three sides 9, 10, and ll. The rail plates are united by their ends to the inner edges of the stiles by means of interlocking 'oints,

as will be understood from Fig. 4, w erein is shown a horizontal sectional view of the center rail 4, comprising the plates 12 and 13. The joint between the respective ends of the rail plates 12, and 13, and the ad jacent edges of the stiles is the same and is formed by fashioning the end of the rail late into a hollow L-shaped groove 14, into which is placed the solid L-shaped part 15, formed on the edge of the stile, the back or inner face 16, of the groove member lying flatly against the inner face of the side 6 of the stile and the ends of both the interlocking L-shaped parts 14 and 15, respectively, projecting inwardly and at right angles to the inner faces of both the rail plate and stile. These interlocking joints are rolled under pressure and provide a firm joint and this same character of joint as 14, 15 and 16, is formed between the upper and lower edges of the rail plates 12 and 13, respectively, and the moldings 17, 18 and 19, 20, as indicated in Fig. 2 at the points 21, 22, 23 and 24, respectively. The rail plates of the upper and lower rails 3 and 5, are likewise secured by their ends to the inner edges of the stiles 1 and 2, and the upper edges of the plates of the lower rail 5, are united to the moldings 25 and 26, respectively, by this same character of joint, as shown in Fig. 2 at the points 27 and 28, respectivel The vertical moldings at each side of t e door panels are also secured to the inner edges of the stiles, 1 and'2, by means of this same character of interlocking joint.

The glass panel 29 in the upper part of the door is held in place by the vertical side moldings 30, 31, which are duplicated on the opposite side of the door and the moldings 17, 18 at the lower end of the panel and the moldings 32, 33 at the uppere'zeud of the panel. It will be noted that the moldings 17 18 in which the lower edge of the panel 29 is firmly set are formed from one piece of metal, which is made up into a substantially three sided hollow body, the free ends of which are formed L-shaped groove, of the peculiar form of tongue and groove joint hereinabove described and referred to by the numerals 14,

into the hollow 15 and,16,'Fig. 4. The two side moldings 30 I as well as the corresponding side moldings 31, may also be made in one piece the same as 17 and 18, whereby there is provided a firm socket or depression 34 (see Fig. 2) in which the lower edge of the glass. is firmly set. The upper edge of the glass panel 29 is held by flanges 35, 36, which project upwardly from the lower edge of the moldings 32 and 33, respectively, and these two. moldings, it will be observed, are formed integral with the rail plates 37 and 38, respectively, of the top rail, though of course these moldings may be united to the rail plates by means of interlocking joints if preferred.

The upwardly extending flanges 35, 36 which clamp the upper edge of the glass, are

embraced by a channel iron 39, which is inverted with the sides projecting downwardly and fitting into sockets 40 and 41, respectively, which are formed between the moldings 32 and 33 and said flanges 35 and 36. A sn'ug'fit is made between these respective parts and the channel iron extends at least the full width ,of the glass panel and is supported and braced in its horizontal position by means of-the brackets 42 and 43 which are i-shaped and depend from a substantial part of the structure in the upper part of the top rail, as will be hereinafter described. The lower end of the brackets are attached to the upper side of the channel iron 39 by means of screws 44 and 45, respectively, and the upper forked ends of the brackets are bent at 46 and 47 and extend through perforations in lugs 48 and 49, respectively, the lugs being securedto the under side of the horizontally extending wing of the angle irons 50 and 51, respectively, the vertical wings of which are Welded to the inner faces of the top rail plates 37 and 38, respectively.

The bent ends 46 and 47 are booked through l spot-welded to the inner face. of the rail the perforations in the lugs 48 and 49 and are held in place therein by reason of the lower ends of the brackets being secured to the 'channel iron 39. When glass is not used in the panel and is replaced by steel plates, these brackets 42 and 43 may be omitted. a

The vertical wings of the angle irons 50 and 51 are provided with inwardly extending ofi'sets 52 and 53, respectively, as shown in Fig. v2, in order to receive the downwardly extending sides of the channel iron 54, flush with the outer sides of said wings. The

channel iron 54 is placed in inverted position in the upper end of the upper rail, and is held in place by screws 55, the threaded ends of which take into threaded sockets in the horizontal wings of the angle irons 50 and 51, respectively. A strengthening bar 56 is placed horizontally on the upper sides of the horizontal wings of the angle irons 50 and 51, respectively, and is removably secured thereto by means of screws 57.

By virtue of having the brackets 42 and 43 hooked in the eyes 48 and 49, and having both the strengthening bar 56 and the channel iron 54, which forms a closure for the upper end. of the door, both detachable, I am enabled to readily gain access to the interior of the upper rail and as the brackets are also detachable by virtue of the screws 44 and 45, likewise the channel gripping iron 39, the interior of this part of the door is made easily accessible for the purpose of painting the same, to protect the parts against rust;

The lower end of the door is closed in the same way as the upper end by means of angle irons 58, 59, having otlsets 60 and 61, res ectively. The channel iron 62' is removaby secured to the horizontal wings of the angle irons by means of screws 63 and the strengthening bar 64 secured by screws 65 to the horizontal wings of the angle irons, all similarly to. that described for the upper end of the door.

Within the lower rail 5 is placed a channel iron 66, the backof which is welded at 67 to the inner face of the lower rail plate 68, while the outer end of the channel iron is pr.:vided with inwardly projecting flanges 69, 70, respectively,which are welded to the inner face of the adjacent rail plate 71. Within the] channel iron 66, near the center thereof is inserted a small channel iron 72, whichhas its open side projecting toward the closed side of the channel iron 66, and which has its two side wings riveted to the channel iron 66 by means of rivets 7 3 and 74, respectively. The open end of the channel iron 66 is closed by a still smaller channel iron 75, which has laterally extending flanges 76 and 76, respectively, which take under the inwardly extending flanges 69 and. 70 of the main channel iron 66, and the back of the channel iron is plate 71. In this way the three channel irons which are thus associated are securely united to the two rail plates of the lower rail and serves to greatly strengthen these plates which are often of considerable depth.

The lower panel [78 of the door, which is generally made of sheet metal, is in the present instance composed of two similar" plates 7 9 and 80 with a thick layer of fire proof material 81, such as asbestos, placed between the two plates, as shown in Fig. 2. These plates are thus kept out of contact and rendered more fire proof than is the case where the two metal plates come together. This lower panel 78 .is held in place by means of the upper and lower moldings 19, 20 and 25, 26 and the Vertical side moldings 82, 83, which are arranged in pairs as indicated in Fig. 2. These moldings of the lower panel are constructed substantially alike and a description of one pair will sufi'ice for all of them. The moldings lfl and 20 are, as previously stated, united at their outer edges to the rail plates by means of the interlocking joints hereinbefore described. The inner ends of these moldings are provided with a rearwardly' extending hook-shaped flange 84, 85, respectively, the nose,or end of the hooked part of which are brought together at 86 and form an abutment for the edge of the layer of fire proof material 81, while the edges of the sheet metal plates 79, 80 are inserted in the hooked part 85 and 84, respectively. These hooked ends of the moldings are spot-welded together at- 86 (see Fig. 2).

A T-bar 87 is placed within the hinge stile with the back of the bar spot-welded to the inner face of the side 7 of the stile, as shown in Fig. 5. One wing of each of the two pairs of hinges 88 and 89, is let into the opening 90 in the side 7 of the stile, and this Wing is secured to the "l'-bar 87 by means of screws 91 and 92.

A look box 93 is placed in the lock stile 2, the ordinary latch of the lock being operated by the knob 9-1 and this box 93 made of a strip of sheet metal which is bent into a rectangular shaped hollow body with the two ends 95 and 96 overlapping each other, so as to form a double wall at that end of the body, and this box is welded within the lock stile to the inner surface thereof as indicated in Fig. 4, the double walled end of the lock box being placed outermost and formed with the registering openings 97 and 98 to register with an opening 99 in the side 10 of the lock stile.

I wish to be understood as not limiting my invention to the precise construction herein shown, as it is manifest that various modifications may be made in different parts thereof Without however departing from the spirit of my invention.
